Noa simply tells the stories of the people living in her mind. The reason all of these stories are full of erotic adventures, sexual fantasies and yummy males is still a mystery but she obviously isn't responsible for that (or at least that's what she says).
Her motto is "Good girls go to heaven, bad girls go everywhere". Maybe that's why she's always off visiting other worlds, even if her home is in the beautiful south of Spain. But just don't try to tell her that she isn't a good girl as that's about as risky as taking away her beloved chocolate or alpha heroes!
